Precursor B-cell Lymphoblastic Lymphoma of the Ovaries: An Immunohistochemical Study and Review of the Literature

Unusual presentation of primary ovarian diffuse large B-cell lymphoma: a case report

Background

Primary ovarian lymphoma has been difficult to diagnose clinically and pathologically due to its rare incidence and non-specific clinical symptoms.

Case presentation

A 75-year-old female patient was reported in this study. The patient had a six-month history of changes in bowel habits, with occasional black feces and paroxysmal pain in the abdomen. The computed tomography scan of the pelvic cavity illustrated that rectal cancer and sigmoid colon adenocarcinoma invaded the lower part of the right-side ureter. The patient was once treated with excision of part of small intestine, fallopian tube and ovary, and uterus. The pathological examination of these excised tissues, combined with the immunohistochemistry, confirmed that the female patient suffered from primary ovarian diffuse large B-cell lymphoma (DLBCL), and the lymphoma had invaded the entire right-side ovary tissues, serous membranes on the posterior surface of the uterus, and the wall of small intestine.

Conclusion

Few reports were available regarding the primary ovarian DLBCL. The initial symptom of the patient was the changes in bowel habits, which had not been reported beforehand. Hopefully, this case could helpfully render the early diagnosis possible, and increase clinical understanding of primary ovarian DLBCL, which would thereby reduce the chance of misdiagnosis.

Lymphoblastic Lymphoma Presenting as Bilateral Ovarian Mass in an Adolescent Girl

BACKGROUND

Lymphomas rarely involve the genital tract and non-Hodgkin lymphoma (NHL) presenting as ovarian tumor is rare. Precursor B-cell lymphoblastic lymphoma arising from the ovary is extremely rare and to our knowledge, only 5 cases have been reported in the literature.

CASE

A 15-year-old girl presented with bilateral ovarian masses, which, on biopsy proved to be precursor B-cell lymphoblastic lymphoma. She was treated with a Berlin-Frankfurt-Munster 90 protocol and she is alive in complete remission for more than 10 years.

SUMMARY AND CONCLUSION

NHL of the ovary should also be considered as a differential diagnosis in adolescent and young adults with ovarian masses. Attempt to make a preoperative diagnosis is crucial because ovarian NHL responds well to chemotherapy and has a good prognosis.

Natural history of primary precursor B lymphoblastic lymphoma of the ovary: report of a rare case

The involvement of the ovaries in lymphomatous processes is a relatively rare phenomenon. Secondary involvement as a part of systemic disease is common as compared to de novo primary lymphoma. Mostly, primary ovarian lymphomas are diffuse large B cell type, whereas the precursor lymphoblastic lymphomas are extremely rare and only four cases have been reported previously. We herein describe a case of primary precursor B lymphoblastic lymphoma involving both ovaries in a 28-year-old woman which was detected incidentally and spread into the blood after 7 months; consequently she succumbed to the disease.

Ovarian lymphoma

The involvement of the ovary in lymphomatous processes is rare. Such an involvement can occur in 2 ways, either primary or secondary, which usually presents with abdominal or pelvic complaints. We present a case of secondary involvement of the ovary with occult extra-ovarian nodal disease and discuss the histogenesis of ovarian lymphomas with criteria for diagnosis and differential diagnosis.

Primary ovarian lymphoma: report of two cases and review of the literature

Ovarian lymphoma is a rare entity. Clinicians should be aware of its clinical manifestations and management since surgery alone often is not adequate treatment. Here, we present two cases of ovarian lymphoma and discuss what is known about ovarian lymphoma.

Rare oral cavity presentation of a B-cell lymphoblastic lymphoma. A case report and review of the literature

Lymphoblastic lymphoma is an uncommon malignancy, with most cases showing a T-cell phenotype and presenting as a mediastinal mass. By contrast, B-cell lymphoblastic lymphoma/leukemia is a rare high-grade malignancy that comprises approximately 10% of all lymphoblastic lymphomas. Lymphomas of the oral cavity are rare and typically present as intraosseous lesions that are most commonly diffuse large B-cell type. Here we present what we believe is the first B-cell lymphoblastic lymphoma initially presenting in the oral cavity. The case involves a 46-year-old white woman who presented with a mass in the right mandible. This report discusses this rare malignancy, including clinical presentation, histopathologic features, immunologic profile, treatment, and prognosis. This case emphasizes the importance of recognizing rare entities that may present in the oral cavity and the impact of the disease and its management.

Lymphomas of the female genital tract: a study of 186 cases and review of the literature

Malignant lymphomas in the female genital tract are rare, and those arising from this tissue system are extremely uncommon. Most pertinent reports lack clear references to the accepted classifications or failed to apply immunomarkers and molecular techniques for a reliable diagnosis. We analyzed a large group of patients with primary and secondary lymphomas of the female genital tract classified on the basis of the recent WHO consensus. A total of 186 patients with malignant lymphoma detected in the female genital tract were selected from the files of the Kiel Lymphoma Registry covering the period of 1974 to 2004. Stringent criteria were applied to separate systemic versus secondary lymphomas. All cases were reviewed on the basis of conventionally stained sections, relevant immunohistochemistry using the alkaline phosphatase/anti-alkaline phosphatase technique, and clinical information, as far as available. When required, gene rearrangement analysis was performed, including TCR-gamma chain gene and the three FR fragments of the IgG heavy chain gene. In addition, typical chromosomal translocations were detected by means of the FISH technique to verify the diagnosis, where needed. Thirty-seven percent of the cases were systemic lymphomas and 63% were mostly extranodal lymphomas primary to the female genital tract. The adnexa were involved in 87 cases, followed by uterine corpus in 23 cases, uterine cervix in 17 cases, portio in 9 cases, vagina in 11 cases, and vulva including clitoris in 8 cases. In 31 cases, two or more adjacent sites were involved. In both (primary and secondary) groups, the adnexa were the prevailing site of involvement. As expected, the overwhelming majority of cases were of B phenotype. The most frequent type of lymphoma proved to be diffuse large B-cell lymphoma, closely followed by follicular lymphoma, including all 3 grades of malignancy. Burkitt lymphoma showed a rather similar frequency. Marginal zone lymphoma occurred exclusively as primary lesions in the uterine mucosa. Lymphoplasmacytic lymphoma was restricted to the vulvo-vaginal area and occurred in women over 60 years of age. In conclusion, our study provides a thorough overview of various types of lymphoma affecting the female genital tract primarily or secondarily, which were classified on the basis of a widely accepted WHO classification. Although quite rare, our report should remind the pathologist of considering malignant lymphomas while reading biopsies taken from female genital organ.
